You don't have permission to use the application "ksfetch"

When i finished install Google update software, It pop up "You don't have permission to use the application "ksfetch"" many times one day, I closed it, it pop up again.
The pop up said"You don't have permission to use the application"ksfetch", For more information,contact the person who set up account"
How can i fix it, does someone know? Thanks very much in advance.

You may need to rebuild permissions on your user account. To do this,boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu. In Terminal, type:  ‘resetpassword’ (without the ’s), hit return, and select the admin user. You are not going to reset your password. Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.

  • How to resolve "You don't have permission to use the application" errors?

    We've been struggling with managed preferences, specifically applications, for a few users. They have mobile home folders which live on a Mac OS X 10.6.x Snow Leopard Server AFP server, preferences which are managed (by group) on a Mac OS X 10.6.5 Snow Leopard Server Open Directory Master, and the clients are running Mac OS X 10.6.4 Snow Leopard (bound to the Open Directory Master). There are also two Mac OS X 10.6.4 Snow Leopard Server Open Directory Replicas. We always manage applications and DO NOT sign the apps when adding them in Workgroup Manager.
    Essentially, key applications are unable to run due to the "You don't have permission to use the application" errors, even though they're explicitly whitelisted. (See some prior investigation over on Serverfault.) After seeing that the Mac OS X 10.6.5 Server update included the following fixes, we upgraded our Open Directory Master to 10.6.5:
    * Addresses an issue that could prevent managed preferences from being applied when a user logs in on a workstation that has been idle.
    * Fixes an issue that could prevent administrators from bypassing client management settings on a workstation.
    This seemed to improve the situation slightly, our most important application now seems to be allowed. Occasionally, it'll give the same error, but a simple log out & back in allows it again. We have not upgraded the client workstations with the Mac OS X 10.6.5 update as it doesn't note any related fixes and we haven't fully qualified it for mass deployment.
    We now have two applications that live in ~/Applications which are explicitly whitelisted (again, NOT signed), which fail with the same error, but logging out & back in does not resolve it. `sudo mcxrefresh -n 'user'` doesn't resolve the issue. In fact, `sudo /System/Library/CoreServices/ManagedClient.app/Contents/MacOS/ManagedClient -f -u `id -u 'username'`` fails with the following error:
    ManagedClient- bad parameter to -u option: use format '-u 501'
    Today I was able to catch the following in /var/log/system.log while attempting to run one said applications:
    Dec 22 17:36:24 hostname parentalcontrolsd[43221]: -[ActivityTracker checkApp:csFlags:] [954:user] -- * Incoming app appears to be masquerading as white listed app and failed signature validation: /Users/user/Applications/FileMaker Pro 5.5/FileMaker Pro.app/Contents/MacOS/FileMaker Pro. Note: This may be a valid app of a different version than what was whitelisted (on a different volume?)
    Dec 22 17:36:24 hostname [0x0-0xa42a42].com.filemaker.filemakerpro[43304]: launch of /Users/user/Applications/FileMaker Pro 5.5/FileMaker Pro.app/Contents/MacOS/FileMaker Pro was blocked
    Dec 22 17:36:24 hostname com.apple.launchd.peruser.1340[6375] ([0x0-0xa42a42].com.filemaker.filemakerpro[43304]): Exited with exit code: 255
    Dec 22 17:36:24 hostname parentalcontrolsd[43221]: -[ActivityTracker(Private) _removeAppFromWhiteList:] [1362:user] -- * Couldn't find local user record
    So, even though the apps are listed in Workgroup Manager and are unsigned, and also appear in '/Library/Managed Preferences/user/com.apple.applicationaccess.new.plist', it appears that the client somehow thinks they don't match what's in the whitelist even thought WE DON'T SIGN THEM WHEN WE ADD THEM!
    What might be causing this? Any further troubleshooting tips would be GREATLY appreciated!

    According to the [Code Signing Guide|http://developer.apple.com/library/mac/#documentation/Security/Conceptual /CodeSigningGuide/Procedures/Procedures.html#//apple_ref/doc/uid/TP40005929-CH4- SW2], it appears that there is no way to remove signing (emphasis mine):
    "You can take a partial-update approach to revising your code on the user’s system. To do so, sign the new version as usual, then calculate the differences between the new and the old signed versions, and transmit the differences. Because the differences include the new signature data, the result of installing the changes on the end-user's system will be the newly signed version. You cannot patch a signed application in the field. If you do so, the system will notice that the application has changed and will invalidate the signature, +and there is no way to re-validate or resign the application in the field.+"
    Upon further investigation, the version of FileMaker 5.5 in question appears to be signed even after a fresh install from original install media. I wouldn't have thought Code Signing was around back then (2001). And the code signing appears to match between the fresh install (to a new location) and the original install. I'll attempt to sign it in WGM and install the same, signed copy everywhere.
    Also, I looked at one of our other working primary applications (4D.app) and it is unsigned, but appears in the Firewall as "Allow incoming connections", so I don't believe that the Application Firewall is necessarily signing apps automatically (but I certainly won't be ruling it out).
    I haven't checked yet, but the other application that's failing is "Parallels Desktop 6", which I'd bet is signed. I wonder if the "Automatically allow signed software to receive incoming connections", which is checked, would come into play at all?
    Thanks for pointing out how to use `codesign` to check whether an application is signed or not, this seems to be the first real break on this case.

  • "You don't have permission to use the application -" pop up in managed account

    Hi All,
    I have Net Nanny installed in my mac.
    When my child login to his managed account the following messages pops up:
    It does not  matter which  of the three choices I click, it keeps popping up.
    In the Safari parental control I have the Net Nanny application allowed.
    Today I deleted Net Nanny from the computer, but the mesage keeps popping up.
    Could anyone please offer a suggestion?

    Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
    Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
    Here are some general guidelines. Suppose you want to remove something called “BrickYourMac.” First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickyourmac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickYourMac.dmg and open it. There may be an application in there such as “Uninstall BrickYourMac.” If not, open “BrickYourMac.pkg” and look for an Uninstall button.
    You may have to log out or reboot in order to complete an uninstallation.
    If you can’t remove software in any other way, you’ll have to erase your boot volume and perform a clean reinstallation of OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
    Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" that purport to remove software.

    Please repost in the Final Cut Pro forum. Have you considered upgrading your machine, if you are still running Leopard your machine may be as old as 5 years old. While this should not matter you probably won't get the performance you want out of a demanding app like FCP.
    Best of luck.

  • Installed Parental Controls on MBP 10.7.5. Now it's unusable (exc admin's acct).  Constant message pops up- "You don't have permission to use (whatev) app." U can click: ok, always allow, allow once, but no matter what, message continues and u can't work

    Hi,
    I installed Parental Controls on our MacBookPro 10.7.5. Now it's unusable (except for my  admin's acct). Constant messages keep popping up that say  "You don't have permission to use (whatever) application." You have the option to  click: ok, always allow, or allow once, but no matter what you select, the messages keep popping up and prevent you from working.  I have searched these forums, and all I have found is that you are supposed to uninstall the application (Spotify, dashboard, etc). Deinstalling every app is not a solution.
    If the parental controls just don't work - and frankly I'm tired of wasting all this time trying to fix the bugs - can someone recommend a program that will restrict certain user accounts to any websites I haven't specified?
    Thanks for any help or advice.

    Thanks Bob for that very fast reply!
    But neither "Modifying hal configuration" nor "Using the Desktop Environment settings" (xfce) worked. So I tried the "I don't want this crap, how do I turn it off?" solution and well it works
    Maybe I turn it back on in a month or so.. but for now i'm fine with no hot plugging but a working keyboard...
    Thanks and Bye!

  • How do I get the history and bookmarks to be functional when my Mac responds with "You don't have permission to rename the item "places.sqlite" as recommended in Solution 2, Part 2 - Create the database"?

    Since installing Firefox 4 on my MacBook OS X version 10.6.7 I've been unable to activate my Bookmarks or history. When logging on Firefox I get an error message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application." When I follow the direction as stated in "The bookmarks and history system will not be functional, Solution 1: Restart your computer," it doesn't help. When I attempt Solution 2: My computer generates, ""You don’t have permission to rename the item “places.sqlite”

    Start at http://www.mozilla.com and download the latest
    version. '''At the completion of the download don't let the setup start Firefox for you, when the setup ends, start Firefox in your normal manner this way you will be less likely to create a new profile.'''
    The extra startup pages are temporary -- read them. The next time
    Firefox comes up you should be back to starting with your normal home page.
    '''Note: Firefox must be down once the install starts. '''
    Close Firefox with File>Exit. Then make sure Firefox is not running --
    On Windows: check the "Processes" tab in the Windows Task Manager.
    '''On Mac: Firefox > Quit then Command+option+Esc, if Firefox running use Force quit'''
    Permission errors on Mac:
    '''If you were getting permission errors on a Mac, download the latest
    Firefox version, then uninstall and reinstall Firefox. Do not remove
    your profile directories and files as they contain your settings,

    in any case once you are on 4.0 you might want to take a look at "(fx4)"

    Hi,
    This problem may occur for one or more of the following reasons:
    A USB media reader device is attached to the computer.
    Removable media is mounted in the computer.
    The .iso file that you are trying to mount is a sparse file.
    To resolve this problem, use one of the following methods.
    Resolution 1
    Copy the ISO file to a new file by saving it to a different folder or giving it a different name.
    This should remove the sparse attribute and enable the file to be mounted.
    Resolution 2
    If you have a flash media reader or any removable media, try to eject the removable media. Then, reassign the drive letters in such a manner that you leave a lower drive letter available to mount the ISO image. The file might not behave correctly if it has
    an assigned drive that follows other drives.

  • Mount vhdx: You don't have permission to mount the file

    The user has all modify permissions on the vhdx file that was created through Hyper-V. When double clicking or right-click mount the vhdx file the error message "You don't have permission to mount the file".
    Which permissions should be set to mount a vhdx file?

    Hi Adm1nMikeW,
    Please try to use disk management --> action --> attach VHD (this way will  avoid  the error message).
    The root cause is the attribute "nodefaultdriveletter" of the backup vhd was not set to "no".
    You can try following setps :
    1. in cmd prompt type diskpart
    2. recognize the problematic volume you want to set via list volume
    3. run command select volume "volume number"
    4. run command attributes volume clear nodefaultdriveletter
    then detach it and reattach the disk again .
    Hope this helps

  • Cannot play shared videos - get "you don't have permission to access the requested resource" error

    When I try to access my shared videos from my iphone 5 (OS 7.01), I get the "You do not have permission to access the requested resource".  The videos I'm trying to play are mine....ripped, not ones purchased from apple.

    I had this problem too.
    I am running iTunes on an old PowerPC MacMini using iTunes 10.6.3. I was trying to stream video on my iPad mini and kept getting the error: "You do not have permission to access the requested resource".
    So, I turned on iTunes on my laptop which is using Mavericks and the latest version of iTunes. It worked fine off it. It's just sometimes I like to keep my laptop in its bag and run things off my iPad through my MacMini.
    So, I did follow the reset network settings on my iPad. It fixed it temporarily. In the middle of an episode of BBT the error message came up again.
    I tried starting iTunes again. I reboot the machine. Still got the error.
    So, I ran Onyx on the MacMini. There were a lot of permission errors on the hard drive. Once I fixed those, it seems I now have permission to access that resource.
    If you have a disk utility, try running it on your source computer to fix any disk permissions or errors that may be causing the error.
    In my case, it was the disk permissions needed repair.

  • "you do not have permission to open the application Dictionary"

    I get the above message when I try to open Dictionary from the Dock or the Finder. However if I access Dictionary from Spotlight it opens. I have repaired permissions and trashed the preference file to no effect. Don't use the application much but it seems to have started after 10.4.9. Thanks in advance for any ideas.
    imac G5 Mac OS X (10.4.9)
    imac G5   Mac OS X (10.4.8)  

    That's weird. If you select Dictionary and do GetInfo on it, then expand the sections at the bottom for Ownership&Permissions, what does it say? Mine, which opens just fine no matter how I launch it, has this:
    You Can: Read&Write
    Owner: system
    Access: Read&Write
    Group: admin
    Access: Read&Write
    Others: Read only
    Don't know whether permissions could be the problem, but it is possible.

  • Spurious error: "You don't have permission to mount the file" on mounting an ISO from Explorer, but it works anyway

    I can mount ISO files from the context menu in Explorer with the new functionality. It works very well.
    However, I have a strange issue with the Microsoft "Linux IC v3.2.ISO" file downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=28188
    Mounting it shows this error:
    But then it seems to mount as a new drive just fine and it is usable. I can also eject it ok.
    I don't have this error with any other ISO. I've tried downloading it twice to different locations, same error. The permissions on the file are normal, same as the other ISOs.

    I have the same problem with my Windows 8 Pro OS.

  • Photoshop CS6 crashing on MAC. You don't have permission to use "AdobeCrashDaemon"

    We are having issue with users unable to open Photoshop on MAC machines at school network. 34 machines that are in the Media Device Group on the profile manager. If remove them from the device group the applications work.
    Product: Adobe CS6 Master Collection
    OS Version: MAC OS X 10.9.4
    Machines: 34 iMAC
    Crash log: Process: Adobe Photoshop CS6 [942] Path: /Applications/Adobe - Pastebin.com

    Well, you have to allow the process and/ or fix your permissions. The error log shows a posix_spawn failure and it also lists various privilege escalation failures, meaning the process never even starts properly due to insufficient privileges. Beyond that nobody can tell you much. This is an issue completely outside the Adobe apps.
